WARP-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 466,555, dated January 5, 1892.

Application filed June 18, 1891. seen No. 396,658. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM CAMPION, a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Warp- Knitting Machines, of which the following is a specification.

My invention relates to warp-knitting machines, and more particularly to that class shown in United States Patent No. 397,140, dated February 5, 1889. In the said knittingmachines the thread-guide bars. are given a longitudinal and. a lateral movement to carry the thread around the needles, and the needles are given a movement in the direction of their length to draw the loops, but considerable lateral movement of the guides is necessary in order to wrap the threads on the needles, and therefore the machine cannot work so fast as it would were the movement of the guides lessened.

It is the object, therefore, of myinvention to and the combinations of parts that will be,

more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein-- Figure 1 is a partly-sectional side elevation of a portion of a warp-knitting machine embodyin g my invention; and Fig. 2 is a vertical longitudinal section on the plane of, the line C C, Fig. 1, showing the relation of the parts connected with the needle-bar.

In the accompanying drawings, the letter A indicates a frame. Bis the cam-shaft suitably journaled in said frame. D is a shaft or bar suitably hung in said frame and carrying the needle-bar levers E and the guide-bar rocking levers F, and G is a shaft also suitably hung in the frame and carrying the guide-bar-supporting arms II. The levers E carry rollers on, that bear on a suitable cam I) (see dotted lines) on the cam-shaft B,-

whereby the levers E are rocked, and thus a longitudinal motion given to the needles I. The levers F also carry rollers d, that are to bear on a suitable cam on the shaft B, whereby said levers are rocked. Thelevers F are connected by links e with the shaft G or with the armsI-I, which latter carry the threadguides J on the guide-bars J whereby the latter may be moved laterally by the levers F. The levers F and thelinks e are to be adj ustably connected together, so that the guides J can be moved more or'less, as desired, and for this purpose I may use a pivot f on the link e, that works in a nut g, carried in a slot h on the lever F, whereby e and F are jointed together. By adjusting the nut g in the slot h more or less motion may be given to the guides, and if it should be desired to have the guides remain stationary it would only be necessary to'remove or disconnect the pivot or pin f, or else disconnect the shaft B or the roller (1 from the cam that operates the levers F. To move the guide-bars J longitudinally, the means shown in the aforesaid patent may be used.

All the foregoing parts may bear-ranged, if desired, substantially as shown in said Patent No. 397,140.

. L is the needle-bar, to which the needles I areor maybe connected by leads 2', as usual, or in any suitable manner. This needle-bar is carried by the needle-bar levers or arms E, and theneedles have a lateral or sidewise motion, (as well as their longitudinal movement,) and for this purpose the needle-bar L is pivaccomplish this I secure to the lever E a foot or support M, by which a shaft or journal N is supported, and from the latter extends a support or bearing 0, that is secured to the needle-bar L, (see Fig. 2;) but it is evident that the details for connecting the needle-bar L pivotally with its lever E can be varied, as may be. desired. I

To impart a lateral motion to the needles and needle-bar, I secure to the needle-bar L one or more arms P, which are preferably forked at the outer ends, as shown, so as to be raised and lowered or rocked by a cam R on the shaft B. The outer ends of the arms P carry rollers j, that slide on the cam R, which latter may be of suitable construction to produce the desired motion. The arm P may otally carried by the levers E, as shown. To

have side projections Z, by which it is to be secured to the needle-bar Ii. \Vith the foregoing arrangement as the cam It rotates it will cause the needle-bar L and needles to be moved sidewise or laterally, because the latter are pivotally carried on the shaft N.

It will be understood that any desired nu n1- ber of levers E F, links 6, arms H 1, supports M and O, and their connecting parts may be used, according to the size of the machine and the work required.

In accordance with my improvements the guides J can be given a diminished lateral n1otion, or, say, reduced to half or less than half that heretofore given, and the needles I will be given a sufficient lateral motion to enable thethreads tobe laid around them. Therefore as the lateral motion of the guides is diminished and a certain lateral motion is given to the needles it is evident that the machine can work faster on account of the small amount of motion necessary to lay the threads around the needles. The longitudinal motion of the needles will act to draw the loops of the threads as usual.

By causing the guides J to remain stationary and giving the needles I a su fficient lateral motion the machine will work, but with a speed reduced compared to the speed when both the guides and needles have a lateral motion.

It is evident that the needles can have a lateral motion imparted to them otherwise than by the forked arm I; but the manner shown gives a very positive action.

Having now described my invention, what I claim is 1. In a knitting-machine, the thread-guides, combined with laterally-movableneedles and means for moving said needles laterally, substantially as described.

2. In a knitting-machine, the laterallymovable thread guides and means for moving the same, combined with laterally-movable needles and means for moving said needles laterally, substantially as described.

3. In a knitting-machine, the laterally-1novable guides, combined with the longitudinally and laterally movables needles and means for thus moving said needles, substantially as described.

4. In a knitting-machine, the combination of the guides with laterally-movable needles, a needle-bar carrying said needles, means for moving said needle-bar laterally, arms or levers E, pivotal supports between the needlebar and said arms or levers, and means for actuating said arms, substantially as described.

5. In a knitting-machine, the combination of needle levers or arms and means for actuating the same with a needle-bar, supports connecting the latter with said arms or levers, needles carried by said needle-bar, and with means to move said needle-bar laterally, sub stantially as described.

(i. In a knitting-machine, the combination of needle arms or levers and means for actuating the same with a needle-bar and with supports connecting said bar with said arms or levers, whereby the needlcscan be moved laterally, a cam for actuating said needle-bar to move the needles laterally, and an arm connecting said needle-bar with said cam, substantially as described.

7. In a knitting-machine, the combination of needle arms or levers, a needle-bar, supports connecting said needle-bar with said arms or levers, an arm I, connected to said needle-bar, and a cam for actuating said arm to move the needles laterally, substantially as described.

8. In a knitting'machine, the needle arms or levers and means for actuating them, combined with supports M, connected to said arms, a needlebar, means for supporting said needle-bar from the supports M, and means for moving said needle-bar laterally, substantially as described.

9. In a knitting-machine, the needle arms or levers and means for actuating the same, supports M, carried by said arms, and rod or shaft N on the'support M, combined with a needle-bar, support 0, connected thereto and also to the rod or shaft N, and means for moving the needle'bar laterally, substantially as described.
